Servicing Pilot Valve Assembly
Note: Assure water supply to sprinkler is positively shut off and all residual pressure has been bled. If sprinkler
is pressurized, main valve will open when the pilot valve control tube is disconnected.
Unless
pilot valve has been previously removed, control tubing length will be sufficient for re-connection.
Selector retains plunger in body.
